Definitions

  • the invention relates to a method for regulating the brake pressure in a vehicle brake system equipped with an electronically controllable brake booster, in which an actuation speed of the brake pedal is determined and a brake force boost is carried out as a function thereof.
  • Such a method is known from DE 40 28 290 C1. It is intended to shorten the braking distance of a motor vehicle in critical driving situations (particularly in the case of so-called panic braking) by using the actuation speed of the brake pedal as a criterion for triggering an automatic braking process.
  • a brake booster known as such is used which generates brake pressures on the vehicle brakes which are no longer determined solely by the force generated by the driver of the vehicle on the pedal, but by other criteria, in particular a comparison of the actuation speed of the brake pedal with a threshold value. If the operating speed of the brake pedal exceeds a threshold value, the braking process is triggered automatically and a brake pressure is built up that is greater than that which would result solely from the position of the brake pedal.
  • the brake pressure on the individual vehicle brakes is not regulated, but rather controlled.
  • an increased brake pressure is built up in such a way that (at Exceeding the above-mentioned threshold value) to the brake pressure, which results from the current pedal position of the brake pedal, an additional brake pressure is generated, which can be, for example, proportional to the maximum operating speed of the brake pedal.
  • DE 39 43 002 A1 a vehicle brake system with a brake booster, in which, in addition to the usual mechanical actuation valve of the brake booster, a further, electrically controlled valve is provided in order to adjust the brake booster (and thus the braking force) as a function of control signals generated by a data processing system .
  • DE-GM 92 02 154 also describes an electronically adjustable brake booster.
  • brake boosters e.g. Brake booster working with a pressure difference
  • an additional electromagnetically actuated control valve so that a brake booster is carried out that differs from the purely mechanically set brake booster, in accordance with the electronic control commands for the electromagnetically actuated control valve of the brake booster.
  • An ideal brake force control using a brake booster could consist in, on the one hand, that of Driver of the vehicle to measure the force generated on the brake pedal and use this force to derive a control signal for the brake booster according to a predetermined function and to generate corresponding brake pressure on the wheels to be braked (possibly under the conditions of an anti-lock control).
  • it is very complex to additionally attach a force sensor to the master cylinder of a brake system.
  • FR-A-2574355 (corresponding to DE 34 44 827) is a method for regulating the brake pressure in a vehicle brake system equipped with an electronically adjustable brake booster, in which an actuation speed of the brake pedal is determined and, depending on this, a brake booster is carried out, during a Braking continuously each time a current actuation speed of the brake pedal a stored or calculated depending on the current actuation speed Setpoint value of the brake pressure is assigned, and at this moment the actual value of the brake pressure is measured and compared with the setpoint value and is set as a function of the comparison result of the setpoint and actual values of the brake booster.
  • the aim of the invention is to use simple means in a vehicle brake system equipped with an electronically adjustable brake booster to adjust the brake booster in such a way that the best possible braking effect is achieved.
  • this object is achieved in that a stored setpoint value of the brake pressure is continuously assigned to a momentary actuation speed of the brake pedal during braking, in that the actual value of the brake pressure is measured at this moment and compared with the setpoint value and in that Dependence on the comparison result of the target and actual values of the brake booster is set.
  • the present invention thus teaches a control of the brake pressure, ie the specification of a target value, the measurement of an actual value and the adaptation of the actual value to the target Value by a corresponding command to the control of the brake booster.
  • the invention is based on the knowledge that it is not necessary to directly measure the input force at the brake booster for an optimal setting of the brake pressure, but that good results can also be achieved in a much simpler manner if the actuation speed of the brake pedal is measured.
  • Such a measurement of the actuation speed of the brake pedal is possible in a simple manner with known rotation angle sensors which measure the rotation of the brake pedal actuated by the driver about its bearing.
  • the rotation path is related to the actuation path of the pedal via a simple geometric relationship, and the actuation speed of the pedal can be calculated by differentiating the rotation path as a function of time.
  • the normalized path s norm , the first derivative (differentiation) of the force over time dF / dt, the first derivative (differentiation) of the path over time ds / dt and the course of the standardized force F norm are plotted here on a common time scale .
  • FIG. 2 shows the result, which is by no means self-evident, that the first derivative of the force over time is essentially the same as the first derivative of the path over time. Therefore, the first derivation of the path over time, i.e. the actuation speed of the brake pedal, can be used as the basis for optimal control of a brake booster, in which the above-mentioned loss of braking distance no longer occurs and in which no expensive and complex sensor for the input force on the brake booster is required.
  • FIG. 1 schematically shows a functional block diagram of a brake system with which the method according to the invention for regulating the brake pressure can be carried out.
  • the individual hardware elements of the device are known as such.
  • the invention resides in the special type of setting of the individual elements as a function of ascertained quantities in order to achieve overall control of the brake pressure.
  • a brake pedal 10 is operated by the driver, ie rotated around the bearing 10 '.
  • the rotation path of the pedal is measured, ie the angle of rotation of the pedal per unit of time.
  • the rotational path measured as a function of time is calculated in order to determine the so-called first derivative (differentiation) of the rotational path over time, that is to say the rotational speed of the pedal 10.
  • a differentiating device 14 is used for this purpose. It goes without saying that one is not necessary for the implementation separate differentiator 14 is required, but that this can be carried out in a known manner in the existing computer of an ABS system (which can also implement the components 14, 16, 18 and 26).
  • the speed of rotation (angular speed) of the brake pedal is linked to its actuation speed via a constant factor. It is therefore equivalent whether the web speed of the brake pedal or its speed of rotation is measured. Measuring the speed of rotation is, however, less complex.
  • the actuation speed v Ped determined in the computing unit 14 is then further processed in order to obtain signals for setting a brake booster.
  • the instantaneous actuation speed v Ped of the brake pedal is continuously (continuously) determined in very small time increments and a setpoint value relating to the brake pressure in the wheel brake of the wheel to be braked is assigned to each instantaneous actuation speed .
  • the wheel to be braked is given the reference number 20 in FIG. 1 and the wheel brake 22.
  • the target values have been stored beforehand and specified for the brake system (which does not mean that they cannot be changed, but they are fixed for a specific braking operation).
  • the respectively applicable value of the actuation speed v Ped of the pedal 10 is thus determined in the manner described above and for each of these time increments the value of the actuation speed v Ped currently measured is then entered Target value is assigned with regard to the brake pressure, which was previously stored in a memory 16 for the given vehicle.
  • the setpoint value can also be assigned to each instantaneous value of the actuation speed v Ped by an algorithm, ie in this variant the box 16 in FIG. 1 would symbolize a computing routine according to which a setpoint value was assigned to each instantaneous value of the actuation speed v Ped becomes.
  • This assignment can be linear in a simple manner, but also stronger than linear, for example according to a function (dependency) of the target value on the value of the actuation speed v Ped , at which the actuation speed v Ped is potentiated, with an exponent greater than 1 .
  • An actual value p Br of the brake pressure is entered into the other input of the comparator 18.
  • the actual brake pressure currently given is measured on the wheel 20 to be braked (one wheel 20 possibly representing a plurality of wheels) in the wheel brake 22, specifically by means of a pressure sensor 24.
  • the target value is to be p
  • the actual value of p Br of the brake pressure compared with each other and dependent on the comparison result signal is supplied to a brake booster control 26th
  • the brake booster control 26 then controls a brake booster 28, which is arranged in a known manner between the pedal 10 and the brake 22.
  • the brake booster control 26 actuates, for example, a special, electromagnetically actuated valve of the brake booster 28 (cf. DE 39 43 002 A1) such that, depending on the result of the comparison in the comparator 18, either the hydraulic pressure generated by the brake booster 28 in the brake 22 increases or is reduced.
  • the brake booster control 26 If the comparison between the target value p to the results from the operating speed of the pedal 10, and the actual value p Br of the brake pressure, which is measured with the sensor 24, that the target value is greater than the actual Value, then the brake booster control 26 generates a signal such that the brake booster effect of the brake booster 28 is increased until the actual value corresponds to the desired value. If, on the other hand, the comparison shows that the actual value is greater than the target value, the brake booster 28 is adjusted in such a way that the brake pressure is amplified less.
  • a favorable brake pressure build-up on the wheel brake 22 can be achieved, in which errors frequently occurring in practice by drivers (which lead to a lead to low brake pressure) can be overcome, namely in that, due to the desired values assigned to the individual actuation speeds of the brake pedal, a higher brake force amplification is set with the brake booster 28 than with conventional braking. This not only accelerates the build-up of brake pressure, it also achieves a higher level of brake pressure. Too high a brake pressure level is conventionally avoided by an ABS system.
